Institute Tirzepatide/Cagrilintide Blend results thread, discussion

Started by NadiaJournal Moderator · · 15 replies · 1,995 views

This happened to me last month and I still don’t totally know what to make of it.

What I want to know is how much of the difference between vendors is real and how much is just measurement noise.

Tried to verify a COA myself by emailing the lab on it. Never heard back. Not sure if that means anything.

The Institute testing page has 2 published Tirzepatide/Cagrilintide Blend reports if you want actual numbers rather than vibes.

Not looking for anything other than what people have actually run into.

Reversed-phase HPLC with UV detection at 214nm is the standard here because the peptide bond absorbs there. If a vendor reports purity without stating the method or wavelength, the number is not comparable to anything.

Three anecdotes is not data. It is not nothing either, but it is not data.

Flagging that we have re-tested this product from a separate lot at a second laboratory. Both results are published.
